VARIOUS CHANGES IN BODY ORGANS DURING THE ANNUAL TRAINING CYCLE OF WATER SPORTS ENTHUSIASTS

Аннотация

Preparation for sports is a complex process that includes training athletes before competitions and participation in them, organization, scientific, methodological and logistical support for training and competition processes, creating the necessary conditions for combining sports and work, study and rest. One of the most effective means, widely used in sports to increase the training effectiveness of exercises and improve the level of athletes' performance, is themethod ofinterval hypoxictraining. The aim of our study was to investigate the body composition and heart rate variability, biochemical and hematological parameters during the annual training cycle in young rowers before and after interval hypoxic training in mid-altitude conditions. The study involved six males aged 21-22 years, actively involved in sports and holding the title of master of sports in academic rowing. Before departure, on the seventh day after arrival, the athletes underwent a body composition study with an analysis of venous blood in the morning on an empty stomach. The parameters of body composition at rest and basal metabolism were estimated by the bioelectrical impedance method using an analyzer. 22 hematological parameters - using an automatic hematology analyzer. The results of the study showed that the average hemoglobin content in erythrocytes of the studied rowers increased significantly after hypoxic training in mid-altitude conditions. In addition, hypoxic training aimed at developing endurance led to a decreasein basal metabolismand total musclemass in thestudied rowers.
